These filters replace 20x20x4 Air Filter perfectly at a very reasonable price. Highly recommended.

I recently went from 1" to 4" filters because they have more surface area meaning they can filter for longer before getting clogged up. I picked these due to the reviews and the high MERV rating. I noticed the length and width of these were less than my previous Filtrete which left a gap. I fixed this by using cutting strips of some Reflectix bubble foil insulation I had and some foil tape to hold it in place on both sides and the back of the air filter housing. This gave me a snug fit preventing air from going around it and is easy enough to remove if I ever need to. These are a great buy after addressing the gap issue.

Great filters, really great price! I really like finding great buys without having to drive to a store and see what is in stock - this is one of those times! I paid more than$30 at Home Depot for one filter, 20x20x4, but, it didn't fit my unit, so I will have to take it back. This is much less expensive, $20 less per filter when buying this 6 pack! This is also MERV 11, which is better quality. You can't beat the price, the free home delivery, and satisfaction guaranteed! My HVAC is happy and running efficiently and clean. I am happy. I recommend you try these!

I was trying to find a filter that was less than 4 inches and when I came across this filter I tried it out and it works just as good as any namebrand filter on the market and it's 3 1/2 inches. I don't know where to find one that size when my air conditioner said it was 4 inches turns out it was a special order filter..

Ça ne s'appliquerait pas ici. C'est un filtre à fournaise qu'on achète régulièrement alors si vous vous attendiez à une revue de ce produit qui couvre tous les aspects, vous allez être déçus. Ça fait le travail, filtre les poussières et empêche ma fournaise de prendre en feu. Good job.
